What does the "Framework" Mean?

When reading tech posts or communicating with your IT friends, how often do you hear the "framework" word? My guess will be that pretty often. And you might not be sure what it means. For example, I thought that a framework is equal to a programming language for quite a long time, which is definitely totally wrong. With a very simplistic approach towards this term, you can say that a "framework" is any set of development tools working together to make software development easier (which means faster and more cost-efficient).

Flutter is a trendy app building framework, along with React Native, which is especially good for creating mobile cross-platform apps. Believe me or not, but there are also low-code/no-code frameworks to choose from.
